Prolon PL-AV20-FSD : VAV Round Damper with Air Measuring Station (flow cross), Diameter 20", Single blade, Air Flow CFM 3100, Velocity FPM 1421, Galvanized Steel Housing, Satin finish, No acoustic insulation
The PL-AV series boxes are a basic, round damper terminal designed for Variable Air Volume (VAV) or Variable Volume and Temperature (VVT) zoning applications. You may also choose to have Prolon’s PL-FSD flow sensor pre-installed from the factory for pressure independent applications.
Characteristics
- Galvanized steel housing, satin finish, 0.8mm (22 gauge)
- Single blade, dual density control damper with Polyolefin insulation seal
- 12.5 mm (1/2”) shaft compatible with most actuators
The PL-FSD air flow sensor is designed and developed to provide an accurate measure of the dynamic pressure corresponding to air velocity through the measurement location.
- The four rods to measure total pressure and the two angular tubes to measure static pressure are coupled to a center core. This center core has two chambers used to centralize, amplify and balance the various measure- ments of total pressure and static pressure
- The location and diameter of the openings for measu- rement on each rod conform to Standard III of ASHRAE
- The aerodynamic shape of the rods and center core mi- nimize static pressure loss, turbulence, and noise level
- The various parts of the velocity pressure sensor are molded out of ABS plastic to achieve the desired strength and durability
- The ABS plastic in use is pre-treated to meet the UL94 standard regarding flame spread in buildings
